ILLINOIS, A CORPORATION OF'lLLINOIS FUSE PULLER Application filedDecember 6, 1926 Serial No. 153,003. Renewed October 19, 1929.

This invention relates to devices of the kind commonly referred to ashigh tension fuse pullers, which are used in'the maintenance of hightension lines for removing and replacing overhead fuses which generallyare located from twenty to thirty feet above the ground.

Oneobject of my inventionis to provide a device of the general typereferred to that can be used successfully for installing or removing aglass expulsion fuse arranged in a vertical or inclined position withoutliability of breaking the glass portion of the fuse and without exposingthe operator to danger.

Another object of my inventionis to provide a device of the generaltypementioned, which, in addition to being capable of use 1 with anexpulsion fuse that is disposed verand tically or in an inclinedposition, can also be used for installing or removing a plug type fuse.

And still another object'is to-provide a device for installing orremoving overhead fuses that is constructed in a novel manner,

which permits it to be quickly'e'ngaged with and disengaged from thefuse that is being removed or installed. I

Figure 1 of the drawings is a perspective view, illustrating my improveddeviceused for installing or removing a plug type fuse.

Figure 2 is a perspective view, illustrating said device being used forinstallingor removing a glass expulsion fusethat 1s arranged 111 aninclined posltlon on an over- R head supporting structure.

Figure 3 is an enlarged view of the device, showing the gripping membersof same engaged with a plug type fuse,

Figure ii is an enlarged view, showingthe gripping members of thedevice, engaged with the glass portion vof an'exp'ulsion'fuse;

F igure. 5 is a side elevationalfviewof the device, taken at rightangles to Figure 4.

My device is designedprimarly t0 be'used for removing or installing aglass expulsion fuse m that is arranged either in a vertical position orin an inclinedposition on an overhead supporting structure, as shown inFigure 2, andit is also capable of being; used for removing'orinstalling a plug type fuse y, as shown in Figure 1. A glass'expulsionfuse comprises a tubular member constructed of glass, and when such afuse is arranged in a vertical or inclined position, it is necessary togrip the glass portion of the fuse and move it laterally or in a generalhorizontal direction, duringtheoperation of removing the fuse from itsholder or introducing it into its holder. A plug typefuse is disposed inits holder in such a way that it has to be subjected to a straightdownward pullto withdraw it from its holder and subject it to a straightupward push to install it in its holderx, Consequently, a device that iscapable of being used with the two different types of fuses abovementioned mustbe of such construction that the fuse gripping members arecapable of being arranged in an angular position with relation to thepole or operating member of the device when an expulsion fuse is belngremovedor lnstalled,

or arranged in longitudinal alignment with the pole or operating memberof the device when a plug type fuse is being removedor installed, inorder that the operator can exert inserted in its holder. illustrated,which represents the preferred form of my invention, has both of thecharacteristics above mentioned, and while I prefer to construct thedevice in this manner, so that it can be used for handling both types offuses that a lineman encounters in the maintenance of high tensionlines, I wish it to be understood that certain features of my'inventionare applicable to a device'designed solely for use with "inclined orverticallydisposed glassexpuls'ion'fuses, and certain features'areapplicable to a device designed solely for use with a plug type fuse.

Referring to 7 the drawings which illustrate the preferred form of myinvention, Adesignates a long pole or operating handle constructedeither from wood'or-from some suitable non-conducting material, B and Cdesignate opposed gripping members arrangedat the upper end of saidhandle and adapted to be engaged with an overhead fuse,

which, as previously stated, may either be a glass expulsion fuse m ofthe kind shown in Figure 2, or a plug type fuse y of the kind shown inFigure 1, D designates as an entirety a head piece on the upper end ofthe operating member A, E designates a rotatable screw ournaled in thehead piece D and connected with the gripping member C, and F designatesa nut connected with the gripi ping member B and provided with an in- Kguide 2 that passes through a hole in a lug 3 on the head piece D. Whenthe screw E is rotated in one direction, after the gripping member B hasbeen engaged with the fuse that is to be removed from its holder, theco-operating screw threads on the nut F and screw E will draw themembers B and C together, and thus cause said members to tightly gripthe fuse, Likewise, when the screw E is rotated in the oppositedirection, the co-operating screw threads on said screw and on thenut Fwill cause the gripping members B and C to separate sufiiciently topermit said members to be disengaged from the fuse after ithas beeninserted in its holder.

The head piece D of the tool herein illustrated is constructed in such amanner that it can be adjusted so as to permit the gripping members Band C to be arranged in an angular position with relation to theoperating member A, as shown in Figure 4, or to be arranged in directlongitudinal alignment with the operating member A, as shown in Figure3. While this can be accomplished i in various Ways without departingfrom the spirit of my invention, I prefer to form the head piece D ofthe tool from a base part 4 and an adjustable top part 5 that is hingedor rockably mounted on the base part 4,

1 thereby enabling the adjustable part 5 of the head piece to be tiltedwhen it is desired to arrange the gripping members B and C so that theyproject laterally from the operating member A. Any suitable means can be5 used for holding the t-iltable or rockable part adjustable portionlike the part 5, and it is also obvious that when the tool is designedsolely for use with a vertically-disposed or inclined expulsion fuse,the head piece D of the tool may be provided with a rigid ornonadjustable part disposed so as to hold the gripping members B and Cat right angles or in an inclined position with relation to theoperating member A of the tool.

Rotary movement is imparted to the screw E by rotating the handle oroperating member A, and while various means can be used for transmittingrotar movement from the handle A to the screw I prefer to provide theparts 4 and 5 of the head piece D of the tool with co-operating gears 7and 8 which are so constructed that they will always remain in mesh witheach other, irrespective of the position in which the part 5 of the headpiece is adjusted, the gear 8 being attached directly to the lower endof the screw E and the gear 7 being attached to a spindle 7, which, inturn, is fastened by a cross pin 7", or in any other suitable manner, toa socket member 9 secured to the upper end of the operating member A.

The gripping members B and C can be constructed in various ways, but Iprefer to use a bifurcated gripping member B that is composed of twohook-shaped portions arranged in spaced relation, as such a grip ingmember can be slipped laterally over tlie reduced shank of a plug typefuse, as shown in Figures 1 and 3, or it can be hooked around thetubular glass portion of an expulsion fuse as shown in Figures 2 and 4.The gripping member C simply consists of a disk-shaped device that isswiveled on the upper end oi the screw E or connected with said screw insuch a way that it will not turn or rotate when said screw rotates. Inorder to prevent the gripping members B and C from chip ping, marring,cracking or breaking the portions of the fuses which said membersengage, the fuse engaging portions of said members are provided withpads 10 of rubber or some other suitable material.

When the device is to be used for removing a glass expulsion fuse of thekind shown in Figure 2, the head piece D of the tool is adjusted andclam )ed in such a position that the gripping mem ers B and C will bedisposed at substantially an obtuse angle with relation to the operatingmember A. Said operating member is then rotated in a direction toseparate the gripping members B and C, and after the member B has beenhooked around the tubular glass portion of the fuse, the operatingmember A is rotated in the opposite direction, so as to draw the membersB and C together and cause them to be tightly clamped to the tubularglass portion of the fuse. After being engaged with the fuse in thismanner, the operator manipulates the pole or operating member A so as toexert a direct outward pull on the fuse, thus causing it to be withdrawnfrom its holder. To install an expulsion fuse the gripping members B andC of the tool are clamped tightly to the tubular glass portion of thefuse while, the fuse is on the ground, and thereafter, the operatorraises the pole-A and manipulates it so as to exert a direct push on thefuse in a direction to force it into its holder. When .the tool is to beused for removing a plug type fuse of the kind shown in Figures 1 and 3,the adjustable part 5 of the head piece D of the tool is swung intolongitudinal alignment with the'base part 4- and clamped in adjustedposition, thus causing the gripping members B and C to be arranged indirect longitudinal alignment with the operating member A. After saidgripping members have been separated by rotating the handle A in onedirection, the gripping member B is slipped laterally over the reducedshank ofthe fuse and the operating member A is then rotated in theopposite direction, so as to close the gripping members, or cause themto tightly clamp the fuse. The operator can then easily withdraw thefuse from its hold or by exerting a direct downward pull on theoperating handle A of the tool.

A tool of the construction above described is easy to operate, as thefuse engaging members of the tool can be clamped tightly to the fusesimply by rotating the operating handle A, and after the grippingmembers have been engaged with the fuse, the operator, by moving thehandle A in the proper direction, can easily pull the fuse out of itsholder. Moreover, such a tool can be used for removing and installingeither plug type fuses or glass expulsion fuses that are arrangedVertically or in an inclined position with out liability of injuring thefuse or subjecting the operator to danger.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is: I
